Title:Can You See Me Now? A Measurement Study of Zoom, Webex, and
Meet

    Abstract: Since the outbreak of the COVID-19 pandemic,
    videoconferencing has become the default mode of communication in
    our daily lives at homes, workplaces and schools, and it is
    likely to remain an important part of our lives in the
    post-pandemic world. Despite its significance, there has not been
    any systematic study characterizing the user-perceived
    performance of existing videoconferencing systems other than
    anecdotal reports. In this paper, we present a detailed
    measurement study that compares three major videoconferencing
    systems: Zoom, Webex and Google Meet. Our study is based on 48
    hours' worth of more than 700 videoconferencing sessions, which
    were created with a mix of emulated videoconferencing clients
    deployed in the cloud, as well as real mobile devices running
    from a residential network. We find that the existing
    videoconferencing systems vary in terms of geographic scope,
    which in turns determines streaming lag experienced by users. We
    also observe that streaming rate can change under different
    conditions (e.g., number of users in a session, mobile device
    status, etc), which affects user-perceived streaming quality.
    Beyond these findings, our measurement methodology can enable
    reproducible benchmark analysis for any types of comparative or
    longitudinal study on available videoconferencing systems.
